Engine Oil Pouring Pipe Outer Wall Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lubricant oil pouring structures for internal combustion engines face challenges in achieving high pouring efficiency while maintaining the rigidity of the pouring pipe, due to limitations in diameter caused by nearby engine components and lack of consideration for efficient oil flow.
Innovation Solution
A lubricant oil pouring structure that includes a pouring pipe with an outer wall surrounding the circumferential surface, enhancing rigidity and featuring a communicating portion between the pipe and a hollow portion, allowing increased oil flow and improved efficiency by enabling lubricant oil to flow from the pipe into the engine through open ends.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the diameter of the pouring pipe is increased to improve pouring efficiency, then the amount of lubricant oil that can be poured increases, but interference with nearby engine components occurs
Solution Approach 1:
The pouring system is segmented into two flow paths: the traditional pouring pipe and the additional hollow portion. This segmentation allows oil to flow through multiple channels simultaneously, effectively increasing the total pouring capacity without requiring an increase in the diameter of the pouring pipe itself, thereby avoiding interference with nearby engine components.
Solution Approach 2:
The hollow portion is nested within the structure of the pouring pipe assembly. The hollow portion is positioned concentrically or adjacently to the pouring pipe, sharing the same vertical space. This nesting arrangement allows the system to achieve increased pouring efficiency without occupying additional horizontal space that would interfere with nearby engine components.
2Stability of the object's composition
If the outer wall is added to enhance the rigidity of the pouring pipe, then vibration resistance improves, but device complexity increases
Solution Approach 1:
The outer wall is designed to serve multiple functions simultaneously: it provides rigidity to the pouring pipe to resist vibration, and it forms the structural boundary of the hollow portion that enables additional oil flow. By making the outer wall multi-functional, the design enhances stability without proportionally increasing device complexity, as the same structural element achieves multiple objectives.
3Productivity
If the hollow portion is opened to the internal space to increase oil flow, then pouring efficiency improves, but oil leakage risk increases
Solution Approach 1:
The outer wall acts as an intermediary structure that defines the hollow portion and controls oil flow. The lower end of the hollow portion is opened to the internal space, but the oil flow is controlled and directed through this structured opening rather than being uncontrolled. The outer wall mediates between the pouring pipe and the internal space, allowing improved pouring efficiency while maintaining sealing reliability through its structured design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The structure enhances the rigidity of the pouring pipe, reducing vibration and improving lubricant oil pouring efficiency by allowing more oil to be poured into the engine through increased communication between the pipe and hollow portion, thus addressing the limitations of existing designs.
Implementation Method 1
The outer wall enhances the rigidity of the pouring pipe
Implementation Method 2
A communicating portion, which allows communication between an internal space of the pouring pipe and the hollow portion, is formed in at least a lower portion of a section of the pouring pipe that is surrounded by the outer wall

AI summary
A pouring pipe (25) projects upward from a head cover body (15), which is a main portion of a cylinder head cover (14), and has a pouring port (32) for lubricant oil (O1) at the upper end of the pouring pipe (25). A filler cap (35) is detachably attached to the pouring pipe (25) from above such that the pouring port (32) is selectively closed and opened. An outer wall (41) is arranged between an outer circumferential surface of the pouring pipe (25) and the head cover body (15). The outer wall (41) surrounds at least part in the circumferential direction of the outer circumferential surface of the pouring pipe (25) with a hollow portion (44) in between. At least part of a lower end of the pouring pipe (25) and at least part of a lower end of the hollow portion (44) are open to an internal space (47) of the head cover body (15). A communicating portion (45), which allows communication between an internal space (46) of the pouring pipe (25) and the hollow portion (44), is formed in at least a lower portion of a section of the pouring pipe (25) that is surrounded by the outer wall (41).
